This thread will compile the links to the threads with the essentials and the great-to-haves. It won't include everything, and you can search for the rest in the downloads section; but it will include the most popular mods. If you feel like other popular mods should be included, post here and I will add it.

Mods or threads that have lots of traffic due to novelty or other reasons will be stickied by themselves until I consider they can be moved here to prevent them from being lost in the depths of the forum.
